Kaitlin Armstrong is a former yoga teacher and real estate agent from Texas who gained international notoriety for the 2022 murder of professional cyclist Anna Moriah “Mo” Wilson. The case, often described by media as a “love triangle” murder, began when Armstrong discovered that her on-again, off-again boyfriend, Colin Strickland, had gone for a swim and dinner with Wilson—a rising star in the gravel racing world whom Strickland had briefly dated during a previous break with Armstrong. Driven by a jealous rage, Armstrong followed them and shot Wilson to death later that night at a friend’s home in Austin.

Following the murder, Armstrong sparked a massive 43-day international manhunt after she fled the United States using her sister’s passport. She traveled through several states before flying to Costa Rica, where she attempted to start a new life by changing her appearance through plastic surgery and using multiple aliases. She was eventually apprehended at a hostel in Santa Teresa, Costa Rica, after U.S. Marshals used a clever tactic: they placed a local advertisement for a yoga instructor, to which she unknowingly responded.

In November 2023, after a highly publicized trial, Armstrong was found guilty of first-degree murder. During the proceedings, prosecutors presented digital evidence showing she had tracked Wilson’s location via a cycling app and security footage placing her vehicle at the crime scene. Before her trial even began, she made headlines again for a failed escape attempt during a medical appointment, where she led guards on a brief foot chase before being recaptured.

As of early 2026, Kaitlin Armstrong is serving a 90-year prison sentence at the Dr. Lane Murray Unit in Texas. She was also ordered to pay $15 million in damages following a wrongful death lawsuit filed by Wilson’s family. The case continues to be a subject of intense public interest, with a new Netflix documentary titled The Truth and Tragedy of Moriah Wilson having just premiered in March 2026, further detailing the events and the impact on the cycling community.

Early Life, Parents, and Family Background

Kaitlin Marie Armstrong was born on November 21, 1987, and raised in the suburban landscape of Livonia, Michigan. Growing up in a seemingly stable, middle-class environment, there were few early indicators of the violence that would later define her adult life.

Parents and Siblings

Kaitlin is the daughter of Michael Armstrong, who has remained a vocal supporter of his daughter throughout her legal battles. Her mother’s details have been kept relatively private, though she grew up in a household that valued education and professional achievement. Kaitlin has a sister, Christine Armstrong, whose identity became a central part of the criminal investigation when it was discovered that Kaitlin used Christine’s passport to flee the United States after the murder.

Childhood and Education

Armstrong attended Stevenson High School in Livonia, where she graduated in 2005. During her school years, she was described as athletic and social. Following high school, she pursued higher education in Michigan, attending Schoolcraft College before transferring to Eastern Michigan University. While her specific degree remains a point of private record, her peers from that era remember her as a driven individual who was deeply interested in wellness and physical fitness—passions that would eventually lead her to become a certified yoga instructor.

Career: From Real Estate to Yoga

Before her name was splashed across news chyrons, Armstrong built a dual career in Austin, Texas. She was a licensed Realtor, specializing in the competitive Austin housing market, and a well-known yoga instructor. Friends and clients in the yoga community described her as “zen” and “calm,” making her eventual transition to a violent fugitive all the more shocking to those who knew her professionally.

She lived a lifestyle common among Austin’s young professionals, often seen at cycling events and outdoor gatherings with her long-term boyfriend, Colin Strickland, a prominent figure in the professional cycling circuit.

The Murder of Moriah Wilson: A Fatal Love Triangle

The catalyst for the tragedy was a complex and fractured relationship between Armstrong and Colin Strickland. The pair had been in a volatile, “on-again, off-again” relationship for several years.

The Encounter

During one of their breaks in late 2021, Strickland briefly dated Moriah “Mo” Wilson. On May 11, 2022, Wilson was in Austin to compete in a race. She met Strickland for a swim at Deep Eddy Municipal Pool followed by dinner. Strickland dropped Wilson off at a friend’s house where she was staying around 8:30 PM.

The Crime Scene

Minutes after Strickland departed, security footage captured a dark Jeep Grand Cherokee—later identified as Armstrong’s—circling the residence. Inside the home, Wilson was shot three times—twice in the head and once in the heart. She was found by her friend later that evening in a pool of blood. Investigators noted the precision of the shots, suggesting a deliberate execution rather than a botched robbery.

The International Manhunt and Escape to Costa Rica

What followed was one of the most dramatic fugitives cases in recent memory. After an initial interview with police—from which she was released due to a technicality in her birth date on the warrant—Armstrong sold her Jeep for $12,200 and vanished.

Fleeing the Country

On May 14, 2022, Armstrong flew from Austin to Houston, then to New York. Using her sister’s passport, she boarded a flight from Newark Liberty International Airport to San José, Costa Rica.

Life in Hiding and Plastic Surgery

For 43 days, Armstrong lived as a fugitive in the beach town of Santa Teresa. To evade capture, she:

Used multiple aliases, including “Ari” and “Beth Martin.”
Dyed her hair dark and cut it short.
Spent over $6,400 on plastic surgery to alter her facial features, specifically her nose and chin.

Arrest and Investigation

The U.S. Marshals Service eventually tracked her down through a clever digital trap. Knowing her passion for yoga, they placed a fake advertisement for a yoga instructor on a local Costa Rican Facebook group. Armstrong responded to the ad, leading authorities directly to her location at a hostel called Don Jon’s.

On June 29, 2022, she was apprehended. At the time of her arrest, she had a bandage on her nose from her recent surgery. She was extradited back to Texas to face first-degree murder charges.

The Trial, Evidence, and Conviction

The trial of Kaitlin Armstrong began in late 2023 and featured a mountain of forensic and digital evidence.

Key Evidence Presented

Ballistics: The gun used in the murder was a Sig-Sauer P365, which was found in the home Armstrong shared with Strickland.
GPS and Tech: Prosecutors showed that Armstrong had used a cycling app to track Wilson’s location and had access to Strickland’s text messages.
DNA: Armstrong’s DNA was found on Wilson’s bicycle, which had been moved from the porch to the bushes.
Security Footage: Cameras captured her vehicle at the scene at the exact time of the murder.

The Second Escape Attempt

In October 2023, just weeks before her trial, Armstrong attempted another escape. While being escorted to a medical appointment, she slipped her restraints and led officers on a 10-minute foot chase through a neighborhood before being recaptured.

The Verdict and Sentence

On November 16, 2023, after only two hours of deliberation, the jury found Kaitlin Armstrong guilty of first-degree murder. The following day, she was sentenced to 90 years in prison.

Current Status in 2026

As of April 2026, Kaitlin Armstrong remains incarcerated at the Dr. Lane Murray Unit in Gatesville, Texas.

Denied Appeals

In January 2026, the Texas Third Court of Appeals officially denied Armstrong’s request for a new trial. Her legal team had argued that she was pregnant at the time of her arrest and that her medical condition should have been used as mitigating evidence, but the court ruled there was “no reversible error” in the original trial.

The $15 Million Judgment

In addition to her prison sentence, Armstrong was ordered to pay $15 million in damages to the Wilson family following a wrongful death lawsuit. This judgment ensures that if Armstrong ever attempts to profit from her story via books or movies, the proceeds will go directly to the Wilsons.

Personal Life and Legacy

Before the murder, Armstrong was known as an outdoors enthusiast who enjoyed hiking and the vibrant Austin social scene. However, the trial painted a portrait of a woman consumed by possessiveness and jealousy.

The case has left a permanent mark on the cycling community. The Moriah Wilson Foundation was established by the victim’s family to support youth sports, turning a narrative of tragedy into one of community empowerment.

Conclusion

The Kaitlin Armstrong Biography is a cautionary tale of how jealousy and obsession can dismantle a life of privilege and promise. From the yoga studios of Austin to the prison cells of Texas, Armstrong’s journey reflects a stunning fall from grace. While she will likely spend the remainder of her life behind bars, the memory of Mo Wilson continues to inspire athletes worldwide, standing as a testament to a life that was taken far too soon.
